Title: Microcomputer device
Inventor: MORIMI YOICHI
IPC: H04M1/50
Filed: 1988-06-02
Abstract: PURPOSE:To generate the DTMF signal of high accuracy with an arbitrary basic frequency by detecting a D-A converting period, loading interruption to a CPU, controlling a correcting block with the CPU and obtaining a prescribed frequency. CONSTITUTION:A CPU8 to control a DTMF circuit sets a dividing ratio to registers 6 and 16 in order to obtain the frequency, which corresponds to a key, when it is detected that the key of a telephone set is pushed. Then, a count value is set to down counters 1 and 11 with preset. When the down counters 1 and 11 start counting and the count value goes to be '0', the count-up signals of n-adic counters 2 and 12 are generated and the interruption is loaded to the CPU8. When the CPU8 receives the interruption, the n-adic counters 2 and 12 are read. Then, when the dividing ratio of the down counters 1 and 11 are changed, a new dividing ratio of written to the registers 6 and 16. Thus, since arbitrary time correction can be executed in the arbitrary block of D-A conversion, the prescribed frequency of the high accuracy can be obtained with the arbitrary basic frequency.

Title: Wire dot printer
Inventor: ONO ATSUSHI
IPC: B41J19/18
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To ensure stabilized printing constantly by altering the driving conditions (driving period and current pulse width) of a print head in the case of a print speed of disadvantageous operational timing for the print head. SOLUTION: A print control section, i.e., a CPU 21 stores character, print position data delivered from an external apparatus in the receiving buffer 29 of a RAM 27. Distances L1, L2 to the left and right ends of a print range are read out from an edited dot data. A print data edition buffer 28 processes two lines of print data at a time and determines a print speed. More specifically, moving speed of a print head carrier is determined such that the carrier is accelerated to a high speed when a long accelerating/decelerating distance can be ensured depending on the distance between the stop position and print position of the carrier where the carrier can be accelerated/decelerated otherwise the carrier is moved at a low speed. According to the arrangement, abrupt acceleration/deceleration is suppressed and stabilized printing is ensured.

Abstract: PURPOSE: To quicken a time of building-up of the rotational speed, with a use of three external terminals made enough as well, by means of constructing a speed controller for the DC motor in a manner of semiconductor integrated circuitry.  
     CONSTITUTION: In a speed control circuit of DC motor 9, a portion surrounded by a broken line, as shown in the drawing, is made by a constitution of semiconductor integrated circuitry, with a connection externally made to a prescribed point by three terminals 19, 22, 30. With the DC motor 9 causing a change of speed in a direction of increasing its speed of rotation, a counter electromotive force of the motor 9 will be raised to lower down a potential of the terminal 22. Consequently, base bias for a transistor 23, for constituting a differential amplifier, comes to be in a deep level, and its collector current increases also with collector current of a transistor 26 increasing, further with collector current of a transistor 27, that constitutes a current mirror, increasing. Accordingly, with base and emitter current of a transistor 31 increasing and base current of a transistor 33 decreasing, and collector current of transistors 11 to 14 decreasing, a control will be operated toward a direction of lowering down a rotational speed of the motor 9.

Abstract: PURPOSE: To reduce the contention of access requests among a plural number of processor only by providing a simple flag register.  
     CONSTITUTION: When processor 1 sends out an access request and an address to be accessed to memory controller 4 at the same time, memory controller 4 detects what memory module among M 1  to M n  the address belongs to, and checks the contents of flag register 10 which corresponds to the address. If not flag register 10 is set, that means no access from any other processor, so that the signal will be sent back as an accessible signal to memory controller 4 via bus 11 at the same time when the flag register is set. By the signal from flag register 10, memory controller 4 sends out a control timing pulse, address signal, write data, etc., to the memory module via bus 5.

Abstract: PURPOSE:To make high speed drive possible and also to improve durability by forming the end turn sections formed at both end of a valve spring slightly larger than the internal side section in diameter. CONSTITUTION:A valve spring 1 for energizing the suction valve and exhaust valve of an internal combustion engine to the direction to close the valves is formed to a coil spring with end turn sections 1a formed at both ends, intermediate section 1c having approximately same diameter, and internal side sections 1b positioned between the sections 1a and 1c and the diameter of which are smaller than these sections 1a and 1c integrated.
